At my work, we tend to do a lot through CLI commands as we have the ability to run them through the CLI on our remote management agent. In case you ever wanted to know what the CLI commands were for changing power profiles, here they are.
This command will list the profiles on the system, placing an * next the currently active profile.
powercfg /l
Here is a list of the profiles with the GUID code.
Existing Power Schemes (* Active)

Here is the command to change the active profile. This one is using the GUID for the High Performance profile (monitor to sleep, but not system).
powercfg /s 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c
